What factors affect the intravenous degree of infusion?

intravenous velocity infusion - usually expressed in cubic centimeters (CC) or millilitres (ml) per hour - is part of a doctor for fluid or medication. In American hospitals, most IVs are filled with computer IV pump to ensure accuracy. IV pumps, however, into the bloodstream was forcibly aroused by liquid. Rather, they allow infusion of drugs in prescribed intravenous infusion despite the relative height of the IV bag and sound an alarm to announce nursing staff if it is unable to instill this amount. Many factors can affect the prescribed or real intravenous infusion, including the IV cannula meter, the location of the cannula IV, the patient's vein and the patient's physical condition.

cannula meter IV or catheter diameter can reduce intravenous infusion speed. Larger channel gauge Numbers, with smaller diameters, have less maximum infusion speed than large necessary cannulas. For this reason, large cannula wells are routinely placed in patients with trauma, surgical cases and transplant patients who regularly require large infusions of IV fluids. In patients who require a large amount of IV liquid very quickly, large cannulas can easily handle a liter or more infusion fluids in a few minutes with an inflated cuff around the IV bag to force fluid infusion beyond what gravity and open line would instill. In the absence of an IV pump, gravity may affect intravenous velocity of infusion, measured by the height of IV bag over the patient's heart.

Another factor that can affect the intravenous rate of infusion is the location of the cannula IV. The more peripheral is the IV location, the slower the maximum rate of infusion, because the veins are smaller further from the heart. IV placed in the hand can therefore handle a smaller volume of fluids than it is possible to place in antecubittal fossa, also known as the inner elbow. Peripheral IV in hands or arms can also cause overRunned interruption of infusion when patients use their arms and crimping blood vessels or IV catheter is unintentionally placed against the living valve. Central lines, such as those that are located in the subclassic vein near the front collar or collarbone, can safely accept higher intravenous velocity of the infusion than the peripheral lines with fewer chances of interruption.

The patient's diagnosis may also reduce the prescribed level of intravenous infusion to prevent risky complications. Patients suffering from congestive heart failure (CHF), kidney disease or other conditions requiring fluid reduction require a slower level of infusion IV. Finally, some IV medicines - for example, chemotherapy solutions - can only be infrased at certain speeds to tolerate the body safely.
